Fish Species

Fish Species

Brown Trout

These were the first of the salmonid species to be acclimatised in New Zealand (in 1867). They are widespread throughout the country in lakes and rivers, achieving body weights in excess of 15 kg. The river fish are distinguished by large black, blue or red spots on the body and a square tail with a few spots. The anal fin has between 10 and 12 rays.

The lake and sea-run fish are silver coloured in summer with dark spots on the body.

Rainbow Trout

Introduced from Californian steelhead stock in 1883 into the Auckland area, and then distributed through the country. They are prolific in lakes, rivers and streams throughout both islands and continue to thrive in an environment that is perfect for their species.

This species has a bewildering array of different forms. Generally the fish have a square tail with radiating spots and a pink stripe may be present along the lateral line. There are spots all over the tail but the rest of the body is usually silver.

Brook Trout

This species was also introduced from California but has not become as widespread as the ubiquitous rainbows. The less aggressive brook trout can’t compete with the rainbow, tend to retreat to stream headwaters and rarely exceed 2 kg.

Bus Pass New Zealand

They are somewhat darker in colour, have a very large mouth and contrasting black and white stripes on their lower fins.

Chinook Salmon

This salmon species is also known in New Zealand as quinnat, another Indian name. They are the largest of the six Pacific species, commonly averaging between 12 and 18 kg.

The sea run and spawning fish have a black mouth and gums, spots covering the whole tail and 15-19 anal fins.


Have a bright red and orange tail and fins and are covered in large shiny scales.


Have two dorsal fins and sharp spikes on the front dorsal fin.


Are distinguished by their deep olive and green body colour.

About the Author:

Danny de Hek
Like most people, I have many passions, goals and dreams. As a self made business professional, my focus is helping my clients, associates and friends, build, strengthen and maintain their success. It would be fair to say I am in the full time business of building relationships and feel my purpose and skill is connecting the right people with the right people. My professional work tends to dominate my personal life, to the horror of my partner and business mentor. They both fully support me yet give me the hard truths when I need to hear this. I am always investing in my personal development to have a fulfilled work/life balance. I enjoy Target Shooting, Hiking & Mountain Biking to clear the brain and to take the guilt away when indulging at a quirky cafe for a cooked breakfast or brunch. My passion for travelling has seen me experience the world on many occasions, my next adventure will be doing the Tibet Rail Journey on the Qinghai-Tibet Railway from Lhasa to Golmud as long as they have Wi-Fi aboard ;-) I have many goals I still wish to achieve but am pretty chuffed that I have accomplished so many of these already.
